United States - Last active: 25 days ago - Tests: 5 - Portfolio: 1

I work with clients on defining, implementing and managing data analysis and data management projects. My expertise lies at the intersection of Statistics, Computer Science and Business acumen. Specific areas of interest to me are education, healthcare, finance, real estate, and energy. Analysis: R (statistics), Python (data munging), Java+Scala (machine learning / big data), VB.NET/Excel (financial modelling) ** Apache Hadoop, Hive, Spark with MLlib (big data ecosystem) ** MongoDB, Neo4j (NoSQL) + MySQL, Monetdb (SQL) ** Gephi (networks/social graph processing) ** Weka (machine learning) Visualization: Tableau (rapid dashboarding), Shiny (R package for interactive statistical dashboards) Environments: Linux, Windows, and Mac (least experience) Productivity: Git (source code control) Web Applications: Play 2 Framework (modern Java/Scala-based, reactive websites) I believe the key qualification to be a Data Science practitioner is an analytic and curious mindset. That said, many hiring decisions seem to hinge on specific skills. Let me know if there's a tool or technology you don't see on my list, and I'll let you know if I've worked with it before.

India - Last active: 3 days ago - Tests: 4

I'm a software developer from India with a breadth of development experience including desktop and web applications using Java, build engineering, and web application development using python/Django. I also have experience in working on components like ADF which is a JSF implementation. Also on wide variety of web servers likes of Tomcat , Apache , Weblogic Server . Unlike many programmers I have a thorough knowledge of my craft and rather than hammer away on projects I use my solid problem solving skills to think through the problem at hand and devise an intelligent solution. I believe in approaching work with a view of scalable long term solutions rather than short term hacks , while honoring the time line. In addition to knowledge in a breadth of programming languages (Java, Python) that I can use to create custom business software solutions, I also am well versed in the administration and maintenance of common web application environments. Programming skills apart, I have a good command of the English language to be able to articulate thoughts very well and that makes me a great Content writer. My ability and skills in researching for information are honed over 10 years of working with many big guns in the Software industry. I can deliver content and articles that perfectly match your requirement, are concise and effective. If you're looking for a moderately priced alternative to American programmers who has the same skill set, ability to communicate effectively in English, and a history of delivering completed work on time and as directed I'm your guy.

Colombia - Last active: 03/22/2013 - Tests: 1

When even was in school, I was fortunate to be good in areas that were difficult for others. He loved math and physics but did not know exactly why. At that moment I had something very clear, I do not want to work behind a boring desk doing paperwork every day. I liked a lot of video games I had installed on the computer and discovered a couple of interesting things about them, so I thought, "If I study related careers with computers, I learn many more interesting tricks." I chose to study systems engineering with the wrong idea, but I found something much more interesting. To succeed it was necessary to read (a lot), learn, share, discuss, and implement. She loved him. For some economic problems, I became a programming teacher of some classmates, so I learned a lot. Since then, and after overcoming many difficulties, I have become a developer, with the programming to continue learning and meeting interesting people. Currently developing applications on Python, Java and PHP (or any other open technology) and I'm learning about Android and new development paradigms.
